Oxcarbazepine is rapidly converted to its active metabolite 10-hydroxycarbazepine (MHD), which is what laboratories actually measure to reflect therapeutic activity. Monitoring helps in evaluating ongoing seizures, suspected toxicity, drug interactions, and pregnancy-related dose adjustments.
This test is used to assess therapeutic adequacy, evaluate suspected toxicity, monitor during pregnancy when levels can change substantially, and when interacting medications are introduced. Sample type is serum.
